Question

network hardware

Hello! Please tell me how to get a pool of IP addresses routed by the provider in Mikrotik and start natit through them.
He sent me something like this:
1.1.1.244/30, route 2.2.2.208/29 next-hop 1.1.1.246

Answer 1

He sent me something like this:
1.1.1.244/30, route 2.2.2.208/29 next-hop 1.1.1.246

this means that the network 1.1.1.244/30 is used to interface with the provider, where .245 is the provider's address, .246 is your address. network 2.2.2.2.208/29 is routed by the ISP through the .246 address (your router). write the address at the junction with the provider and add addresses from the routable pool where you need
